Monday night: Tau Herculid Meteor Shower, Possible Storm

There's some talk that a usually obscure meteor shower, the Tau Herculids, may this year become a meteor storm.

For details, see EarthSky News: Will the Tau Herculid meteors produce a storm?

The Tau Herculids come from periodic Comet 73P/Schwassmann-Wachmann, which in 1995, began to break up, creating lots of debris scattered across its orbit. It's hard to know exactly where the fragments ended up ... but comet experts like Don Machholz think there's a good chance that we'll be passing through an unusually dense clump of particles when we cross 73P's orbit this year.

I'm not a big meteor watcher — I find most meteor showers distinctly underwhelming. But in November 2002, I was lucky enough to view the Leonid meteor storm from Fremont Peak, near San Juan Bautista, CA.

A Brood of Small Cicadas

Our trees in La Senda have been ticking madly for about a week.

The noise had been worrying me. Some of our drought-stressed piñons might not have enough sap to fight off bark beetles (we lost four trees last year to the beetles). On the other hand, cicadas do make clicking noises (like an orchestra tuning up, preparing for the symphony). And the ticking noise came from junipers as much as piñons; bark beetles are usually species-specific..

But eventually we were able to find a few of the tickers and photograph them. Definitely cicadas, though they're noticeably smaller than the big broods of 2014 and 2019, and greener, with bigger eyes (here's a 2019 cicada for comparison).

It's remarkably hard to locate cicadas to photograph them, even when you're surrounded by junipers that each have several of them clicking loudly. Once you see them, you can see the movement as they make their ticking noises, and as they slowly work their way along a branch.

Sending Mail via Gmail using OAuth2 (2022 Edition)

Update: Google's OAuth2 turns out to be not a good way to send mail, because passwords have to be renewed weekly. So you probably want to use a GMail App Password instead. I'm leaving this article up in case there's some reason someone would actually want to use OAuth2 with GMail.

There's been lots of talk on mailing lists for various mail programs, like Alpine and Mutt, about Google's impending dropping of password access.

Although my regular email address is on a Linux server, I subscribe to several Google Groups. I use a gmail address for those, because Google Groups doesn't work well with non-gmail addresses (you can't view the archives or temporarily turn off mail, and unsubscribing may or may not work depending on the phase of the moon).

I prefer not to have to sign on to Google and use the clunky browser interface when I have a perfectly good mailer (I use mutt) on my computer. I send mail from mutt using a program called msmtp. But to post to a Google Group, I need to use Google's SMTP server. (SMTP is the Simple Mail Transfer Protocol, the way mail gets from one computer to another across the internet.)

Up to now, I've been using an msmtp configuration that includes my Gmail password. That requires clicking through several Gmail pages to enable the "Less Secure Apps" setting. Google resets that preference every month or so and I have to go find the "Less Secure Apps" page to click through the screens again; but aside from that, it works okay.

But now Google has announced they'll be removing support for password access on May 30, 2022.

Time-Lapse Video of Pyrocumulus from the Hermit's Peak Fire

The Cerro Pelado fire that was threatening Los Alamos is mostly under control now (71% contained as of Tuesday morning), and the county has relaxed the "prepare to evacuate" status.

That's good, and not just for Los Alamos, because it means more people who can fight the much larger Hermit's Peak/Calf Canyon fire, currently 26% contained and stretching over a huge 299,565 acres.

For those of us on the Pajarito Plateau, that means we're getting views of enormous pyrocumulus clouds towering over the Sangre de Cristo mountains from Las Vegas to just south of Taos.

I keep missing the opportunity for photos, but on Sunday night I took a series of images and made this time-lapse movie.

Mapping Fire Perimeters

I've been using the Wildland Fires map from MappingSupport.com to keep an eye on the Cerro Pelado fire and the larger (though more distant from me) Hermit's Peak/Calf Canyon fires raging in the Pecos.

It's an excellent map, but it's a little sporadic in whether it shows the fire perimeter. In any case, as a data junkie, I wanted to know how to get the data and make my own display, maybe for a quick viewer that I can pop up when I sign on in the morning.

Also, Los Alamos County, on its Cerro Pelado Information page, has a map showing the "Go" lines (if the fire crosses these lines, we have to evacuate) for Los Alamos and White Rock and I'd like to be able to view those lines on the same map with the fire perimeter and hot spots.

Earth, Wind and (Cerro Pelado) Fire

It's the windy season, and the winds are crazy here. I'm pretty sure I saw a house, some flying monkeys and a woman on a bicycle fly past the window twenty minutes ago.

I'm not sure precisely how crazy — our weather station is only showing a max of 18 mph, which mostly means there are too many trees around it, but the weather station at TA54 just up the road is reading 26 right now, with a max of 48.3.

The cage that I built this spring to keep the deer away from the apple tree (not that it ever flowers or fruits anyway) keeps wanting to slide into the tree or topple over on top of it. I had to jump up twice during dinner and run out to rescue it. So now it's tied to some big rocks and, if those lose their grip, it's also tied to the fence.
